I'm genuinely sorry to hear that you guys are having issues with Nexus, but keep in mind that there were a WHOLE BUNCH of these things built. Human error and mass production quotas always yield a few bad apples in the bunch... if a company can get a 99% QA check on any production line, that's a great percentage! But that also means that much of that 1% will eventually fall into consumers' hands.
When you consider the many thousands of people who have had NO problems with their Nexus, put up against the relatively small number of complaints posted in forums like this (you'll find very few posts about "perfect" phones), then the chances of getting a bad phone are very small: but still there.
If you did get a bad phone, or even a couple of them (maybe they came from the same batch or factory?), keep trying. You WILL get a phone that works and works well. And when you do, don't hesitate to tell us about it!
A great many folks in forums post the bad stuff about their phones but not enough of the good stuff, creating the illusion of an overall bad device. There is little remedy for that, save for people like Saint and me who will proudly tell the world that our Nexi work as promised and even exceed our expectations.
Unless you're somewhere on the bleeding edge of Verizon signal, my advice is to JUMP IN on Nexus. It's a safe bet you'll get a phone that's just fine, and will only improve with time.
